Sika® Air-60

AIR-ENTRAINING ADMIXTURE FOR CONCRETE

Sika® Air-60 is an aqueous solution of a unique, synthetically manufactured surfactant for the air entrainment of concrete. It is specifically designed with a lower active material content for concrete where low dosages of air-entraining admixtures are required. It also allows for air entrainment in stiffer concrete mixes. The admixture increases the durability of concrete, making it more resistant to the damaging effects of freeze/thaw cycles, while improving workability and reducing bleeding. Sika® Air-60 is carefully formulated and subjected to stringent quality control in order to ensure superior results in both the plastic and hardened concrete.

  • Superior resistance to freeze thaw cycles and scaling
  • Improves workability
  • Reduces bleeding
  • Reduces size and number of capillary channels; increasing impermeability
  • Increased compressive strength in lean mixes
  • Substantially increased durability
  • Increases moisture retention for cement hydration
  • Superior air void system

Usage

  • For exposed concrete using low slump mixes
  • Production of concrete pipe; vibrated precast such as boxes, culverts, transitions, risers, catch basins; highway paving; curb and gutters; sidewalks; driveways and all other concrete which is subjected to freeze thaw damage or the harmful effects of de-icing salts
  • To increase the workability of concrete, especially in lean or harsh mixes

Application

Application Information

Mixing

Sika® Air-60 can be dispensed into any of the concrete constituents except cement, slag or fly ash. It is preferable to dispense it into the sand. Sika® Air-60 is compatible with other Sika® admixtures. However, each admixture should be added separately to the mix.
Consumption

Recommended Dosage

The recommended dosage range for Sika® Air-60 is 30-1500 mL/100 kg of cementitious material.
 

Note: concrete constituents, slump, ambient air temperature, additions of pozzolanic materials, mixing time, and type and brand of cement will affect dosage rates. It is suggested that trial mixes be conducted, in order to determine the dosage needed to obtain the required percentage of entrained air. In addition, a regular program of air tests should be instituted in order to adjust the dosage to changing conditions. Contact Sika Canada for advice.
